| Abstract |
|
We had carried out a retrospective analysis which consisted of 61 consecutive cases on disability evaluated and estimation of loss of efficiency in this hospital for the last five years. Factors in disability evaluation were decreased visual acuity (27 patients, 44.2%), contracted visual field (5 patients, 8.1%) and disabled ocular motility (15 patients, 24.5%). Estimation errors in disability evaluation occurred in 9 (14.7%) in all cases. The average error rate was 10.2%. The causes were confusion of efficiency with loss of efficiency, conversion deficiency of 75% visual efficiency in pseudophakic eye and estimation errors in diplopia field test. Beforehead estimation cases in disability evaluation were 9 cases (4.7%). The case which needed request of calculation of medical fee after this were 19 cases (31.3%). The incidence of malingering were observed in 11 patients (18.0%) and the major factor of malingering was decreased visual acuity (8 patients, 72.7%). In conclusion, with the use of the estimation of loss of efficiency, we presented many problems such as estimation errors, beforehead estimation cases in disability evaluation, maligerings, request of calculation of medicalfee after this, and etc. Therefore, in accord with the actual condition, we request the establishment of standardization, methods, articles of estimation. |
